I've never seen this error and I didn't find it in Alloy's kb, but that 'pwd' makes me think it's a password issue. I'd check the root password of that mac to make sure it matches what you have set in Discovery.

I'm still encountering the same error. I have confirmed that remote access is enabled on the mac. As for the KB article, I'm only using their trial version to see if we want to purchase the software, so I apparently I cannot read it. Please advise.

honestly I don't know. I'm just going on the info alloy has in their article. I'd contact support personally. you said you're evaluating but I know they provided me with support during my evaluation. keep us posted on the solution.
